LEOPOLD ll. VOGEL, OF JAMAICA PLAIN, MASSACHUSETTS.

WINDOW-FASTENING DEVICE.

To all whom it may concern:

Be it known that I, LEOPOLD H. VoGEL, a citizen of the United States, residing at Jamaica Plain, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Window-Fae tening Devices, of which the following is a specification.

This invention relates to improvements in window fastening devices, and the object is to provide a window fastener which shall be simple and inexpensive in construction and which cannot be unlocked from the outside, and the object is further to provide a fastener of this character by means of which the sashes may be securely locked to each other when partly opened.

A still further object of this invention is to provide a window fastening device which will draw the two sashes firmly together so as to prevent air entering therebetween and which will in addition prevent the sashes from rattling one against the other.

The invention consists in the combination I and arrangement of parts set forth in the fol lowing specification and particularly pointed out in the appended claims.

Referring to the drawings: Figure 1. is an elevation of a portion of a window showing one embodiment of my invention secured thereto. Fig. 2 is a sectional elevation taken on line 2-2 of Fig. 1, looking toward the right.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring now to Figs. 1 and 2, 11 and 10 are upper and lower sashes, respectively, of a window. A plate 12 is secured to the upper face of the lower sash 10 by means of screws 13, while a second plate 14 is secured to one of the vertical port-ions of the upper sash 11 by means of screws 15, said plate 14 being set into the upper sash with its front face flush with the front face of said sash. The plate 14 is provided with. an inclined recess 16 terminating at its upper end in ashoulder 17, said recess being adapted to receive an arm 18 pivotally connected by means of a pivotal pin 19 to the plate 12. A screw 20 provided with a head 21 has screwthreaded engagement with the plate 14, said screw being also provided with a reduced portion 22 which extends through a hole 23 in the arm 18, said hole being elongated or slotted vertically.

Specification of Letters Patent.

Application filed June 15, 1908.

Patented May 25, 1909.

Serial No. 438,498.

The reduced portion 22 is of such extent that when the screw 20 is rotated in the proper direction to unscrew it from the plate 14, said reduced portion permits the arm 18 to rock on its pivot and permits a change in the angular relation of said arm and said screw to take place during said unscrewing, yet when the screw is entirely disengaged from the plate 14, said screw remains permanently connected to the arm 18 so that said screw cannot become lost. When it is desired to open the window, the screw 20 is disengaged from the plate 14 as just described and the arm 18 is swung downwardly toward the right, Fig. 2, out of the recess 16. When it is desired to lock the window sashes to each other when the lower sash is raised somewhat or the upper sash lowered somewhat as suggested in dotted lines in Fig. 2, this may be done by providing the upper sash with a second plate 14 located above the lower one and the screw 20 is connected to this plate in the same manner in which it is shown connected to the lower plate.

It will be noted that the relations of the parts is such that there can be no rattling of the sashes with relation to each other and that the fastening device cannot be unfastened from the outside by introducing a tool between the two sashes.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

1. In a window fastening device, a plate adapted to be secured to one sash, a second plate adapted to be secured to a second sash, an arm pivotally connected to said second plate, and a screw journaled in said arm having screw-threaded engagement with said first-named plate and adapted to hold said arm in substantially fixed relation with said plate.

2. In a window fastening device, a plate adapted to be secured to one sash, a second plate adapted to be secured to a second sash, an arm pivotally connected to said second plate, and a screw journaled in said arm and permanently secured thereto and having screw-threaded engagement with said firstnamed plate and adapted to hold said arm injsubstantiallyfixed relation with said plate.

3. In a window fastening device, a plate adapted to be secured to one sash, a second plate adapted to be secured to a second sash, an arm pivotally connected to said second plate, said arm provided With a hole therethrough, and a screw provided With @11 annular groove sul l oupding ereduced portion which extends through said hole, said screw 5 having screw-threaded engagement with said first plate.

in st mony whereo I v er nt set my hand in presence of two subscribing Wit messes.
